Subject[PATCH 1/4] msm_serial: Use relative resources for iomem
Date
Device tree iomem resources are only accessible by index, and not by
name. The msm_serial devices always have either 1 or 2 iomem
resources, that are always in the same order. Convert the
platform_get_resource_byname into just platform_get_resource to
facilitate device tree conversion.
